Premise of the Study Understanding the relationship between phenotypic evolution and
lineage diversification is a central goal of evolutionary biology. To extend our understanding …

Discerning relationships among species evolved by reticulate and/or polyploid evolution is
not an easy task, although it is widely discussed. The economically important genus …

The Balkan Peninsula, with many endemic species, is known as one of the most important
speciation and diversification centres in Europe. Here, we present a study of the western …

Morphological characters, AFLP markers and flow cytometry were used to investigate the
morphological and genetic variability and differentiation of V iola reichenbachiana and V …

Plant production practices can influence the genetic diversity of cultivated plant materials
and, ultimately, their potential to adapt to a reintroduction site. A common step in the plant …

There was a wave of whole genome duplications (WGD) during and subsequent to the K-Pg
interface, which was followed by an increase in the proportion of species that were …

The phenomenon of polyploidy and hybridization usually results in novel genetic
combinations, leading to complex, reticulate evolution and incongruence among gene trees …

A phylogenetic network is a rooted acyclic digraph whose leaves are uniquely labeled with a
set of taxa. The tree containment problem asks whether or not a phylogenetic network …

Although hybridisation through genome duplication is well known, hybridisation without
genome duplication (homoploid hybrid speciation, HHS) is not. Few well-documented cases …

Woody perennial plants on islands have repeatedly evolved from herbaceous mainland
ancestors. Although the majority of species in Euphorbia subgenus Chamaesyce section …
